A multisensor convex linear statistic fusion modal for optimal interval estimation fusion is established. a gauss - seidel iteration computation method for searching for the fusion weights is suggested. in particular, we suggest convex combination minimum variance fusion that reduces huge computation of fusion and yield approximately optimal estimate performance generally, moreover, may achievers exactly optimal performance in some cases
建立了一種最優區間估計融合模型? ?多傳感器凸線性組合，並給出搜索最優權系數的gauess - seidel迭代演算法，另外，給出了一種近似的區間估計融合? ?凸線性組合的最小方差融合，它能減少大量的計算量。 -
( 4 ) the results of qtl mapping indicated that the inheritance of yield traits was very complex, the explanation as follows : additive effects except for sterile spikelet number per spike ( ssns ), qtls of additive effects were tested for all other traits, with 10 qtls for 1000 grain weight ( kgw ). the large variance of the effect values and the contribution rate of qtls indicated that the effects are difference for different qtls
14 。 （ 4 ）通過對產量性狀qtls作圖，發現產量性狀的遺傳非常復雜，可以從4個方面說明：加性效應除不孕小穗數外，各性狀均檢測到了表現加性效應的qtls 。其中，在各環境聯合分析下，檢測到了10個千粒重qtls ，各qtls的加性效應值和對群體變異的貢獻率也存在很大差異，說明不同的qtls不是等效的。 -
In addition, super - short term strategies also earn significantly positive returns. nevertheless the contrarian strategies under long formation horizons and holding horizons ( beyond 36 weeks ) may yield significantly positive returns. we also find, considering markert factor ( market return, cross - sectional variance of equity returns ) and characteristic of individual stock ( trading volume, firm size, price, price / earnings, be / me ), there exist clearer and more significant patterns of profitability in momentum or contrarian strategies
具體而言，大體上以中短持有期的慣性策略（持有期4 ? 24周）有較顯著之利潤，超短期形成期的慣性策略在1 ? 12周的獲利性亦很顯著，而較長形成期（ 36周以上）與較長持有期搭配的反向策略則可能獲得顯著的正收益。 -
In 1952, h. m. markowitz published an article called " asset selection : efficient decentralization of investment ". he adopted the expectation yield of risk asset, and, at the same time. adopted variance ( or standard deviation ) which represents risk, for the study of selection and combination of asset. this is called the jumping - off point of the modern times asset combination theory by financial circles. after then, william. f. sharpe advanced capital asset pricing model. the study of modern tunes asset combination theory in our country began in 1990 when markowitz and sharpe gained the nobel prize, such as fei fang yu ( 1994 ) and bei duo guang ( 1996 ) published several kinds of bookmakings which introduced modern times asset combination theory, simultaneity, yang gui yuan ( 1995 ), tang xiao wo ( 1994 ) published several articles which discussed the ways how to comformate efficient asset combination in modern times asset combination theory
之後，威廉?夏普（ william . f . sharpe ）又提出了資本資產定價模型。我國對現代資產組合理論的研究是從1990年馬柯維茨和夏普等人獲得諾貝爾經濟學獎開始的，如費方域（ 1994 ）和被貝多廣（ 1996 ）等出版了幾種介紹現代資產組合理論的著作。楊桂元（ 1995 ） 、唐小我（ 1994 ）等發表了不少討論現代資產組合理論中構造有效資產組合理論方法的文章。 -
The results of variance analysis showed that anstar and gannong no. 1 had the characteristics of good stability, high yield potential, strong regeneration and so on, which were favorable in planting on large areas
結果表明，安斯塔、甘農一號苜蓿生產穩定性好，產草量潛力較大，再生性強，綜合性狀好，適宜在當地大面積推廣種植。
